The ruling on reciting Al-Fatihah or something from the Qur'an for the Deceased at his Grave

Question :

Is it permissible to recite (Surat) Al-Fatihah or some- thing from the Qur'an for the deceased when visiting his grave and does that benefit him?

Answer:

It has been confirmed from the Prophet that he used to visit the graves and supplicate for the deceased with supplications that he taught his Companions and that they learned from him. From that is the saying:
"Peace be upon you, O people of the abodes of the believers and the Muslims. Verily we, if Allah wills, will join you. We ask Allah for well-being for us and you."

It is not confirmed from him (that he recited any Surah or Verses from the Qur'an for the deceased, even with his numerous visits to their graves. If this was legislated, he would have done it and explained it to his Companions, due to his desire for reward and mercy for the Ummah and his fulfilling the obligation of conveying (aspects of the religion). For verily he was as Allâh described him:
"Verily, there has come to you all a Messenger (Muhammad from among yourselves. It grieves him that you should receive any injury or difficulty. He is concerned for you, and kind and merciful to the believers."

So, since he did not do that, even though the reasons for him to do it were present, this proves that it is not legislated. The Companions knew that, so they followed his path, sufficed themselves with the admonition (from reflecting upon the condition of the dead) and supplicating for the deceased when visiting their graves. It is not confirmed from them that they recited any Qur'an for the deceased. Hence, the recitation for them was considered a newly invented innovation. Indeed it has been confirmed from the Prophet that he said:
"Whoever introduces into this matter of ours that which is not of it, then it is rejected."
